Update to 3.3.2:

FFTW 3.3.2

* Removed an archaic stack-alignment hack that was failing with
  gcc-4.7/i386.

* Added stack-alignment hack necessary for gcc on Windows/i386.  We
  will regret this in ten years (see previous change).

* Fix incompatibility with Intel icc which pretends to be gcc
  but does not support quad precision.

* make libfftw{threads,mpi} depend upon libfftw when using libtool;
  this is consistent with most other libraries and simplifies the life
  of various distributors of GNU/Linux.

FFTW 3.3.1

* Changes since 3.3.1-beta1:

  - Reduced planning time in estimate mode for sizes with large
    prime factors.

  - Added AVX autodetection under Visual Studio.  Thanks Carsten
    Steger for submitting the necessary code.

  - Modern Fortran interface now uses a separate fftw3l.f03 interface
    file for the long double interface, which is not supported by
    some Fortran compilers.  Provided new fftw3q.f03 interface file
    to access the quadruple-precision FFTW routines with recent
    versions of gcc/gfortran.

* Added support for the NEON extensions to the ARM ISA.  (Note to beta
  users: an ARM cycle counter is not yet implemented; please contact
  fftw@fftw.org if you know how to do it right.)

* MPI code now compiles even if mpicc is a C++ compiler; thanks to
  Kyle Spyksma for the bug report.
